As evening light fades, bright light from the electricity-hungry Canary Wharf docklands development is supplied by the voltage from electricity cables and supporting struts at West Ham sub-station, Canning Town, London England. A network of 110 miles of cables have stretched across 542 'L6' pylons across England's Kent countryside, from the coal-fired power station at Dungeness to this location, carrying 40,000 Volts along this network of aluminium cables to power some of London's high supply demands. Such insatiable appetites for raw power means electricity is now an expensive comodity after climbing oil prices doubled electricity utility bills for some domestic users.
